| Abstract: | The project situation of the new Yamen long-span transmission tower was introduced. The principle of the tower for static computation was presented. The dynamic characteristic of the tower with and without electric elevator were compared. The stiffness between the new and the old Yamen Transmission Tower are analyzed. The wind vibration coefficient of the tower was computed. Finally the detail design of structure joint, anchor bolt, rest platform and walkway for the tower were presented. The design can be provided a reference for design of similar long-span transmission tower. |
